Contrast is what unattractive people with light to medium skin tones use to overexpose their photographs into a somewhat alien-like being that is so ambiguous that it might be hot. There is usually a large, vague blast of light where there would normally be a nose on an actual human being.

Contrast is a form of visual trickery online similar to a FGAS. It can hide a sizeable nose, unattractive bone structure, acne, copious amounts of unwanted facial hair and pretty much anything. Be weary of the glowing siren on your internet message chat session, for underneath the heavenly glow a beast may lurk.

Bro1: Yo bro, check out this chick I met on mybook. She's kind of hot right?
Bro2: I dunno bro, looks like underneath all that contrast she might be sasquatch.
